This invention relates to improvements in tape markers for ropes.

It has heretofore been attempted to produce, on a commercial basis, acompact paper 5 tape of sul'iicient tensile strength to permit it to beused under circumstances where it may withstand stresses and bendingwithout being quickly destroyed. More particularly, it has been soughtto produce a paper tape capable of carrying printed matter and capableof being introduced a into various forms of cordage for the purpose ofidentifying the latter after having been subjected to various usageswhich would ordinarily '15 destroy or render indefinite otheridentifying means. Such prior attempts have been rather successful,although the cost of producing paper tape markers of this character hasbeen higher than the trade considers to be entirely reasonable.

One object contemplated by the present invention is the provision of apaper tape which may be produced at a comparatively low cost and whichis entirely capable of use as an identifying marker for cordage of alltypes.

In the accompanying drawings, 7 Figure 1 is a perspective view of amarker embodying the present invention; and

Fig. 2 is a more orless diagrammatical illustration of the methodemployed for pro ducing markers according to the present invention.

In the present tape illustrated, a continuone flat ribbon of paper iswound spirally in tubular form, of required cross sectional dimension,with the successive convolutions overlapping. After the formation of thetubularly-shaped member the same is 40 pressed into flat, tape-likeform, such as shown in Fig. 1. Preferably, each convolution overlapsone-half of the next preceding convolution, whereby the finished tapewill be of'uniform thickness throughout its entire length.

overlap of the successive convolutions is not, however, an absolutenecessity.

In the diagrammatic illustration of the method of producing the presenttape there is shown a tape slightly different from that initiallyproduced.

This particular degree ofv illustrated in Fig.1. This difference residesin the fact that the tape illustrated in Fig. i 2 is composed of aplurality of ribbons whereby the thickness, and of course the strength,of the finished tape is increased over that of the tape shown in Fig. 1,In the making of the tape the paper in flat, ribbon-like form 10, of thedesired breadth, is first wound spirally with the convolutions 11overlapped to the desired extent. The tube of paper thus formed is thenpassed between compressing rolls 12 and compressed into substantiallyflat tape-like form. As will be apparent, the thickness and strength ofthe finished product may be varied at will, depending upon the number ofribbons 10 used in the initial step of making up the spirally wound tubeof paper. Likewise, the breadth of the finished product is readilyvaried it will depend entirely and solely uponthe diameter of the tube Apaper tape made in accordance with the presentinvention Will be foundhighly capable for use as a carrier for identification data in'cordageof all types, while, at the same time, it may be produced at acomparatively low'eost due to the simplicity of the mechanism requiredfor the carrying out of the process of producingit. V r

It should be addedthat it may be found desirable to treat the paperwithsome suitable adhesive in orderto insure the convolutions retainingtheir proper relative positionsg It should also be pointed out thatafter the spirally wound tube has been com-.

pressed into'its final fiat, tape-like fornn'it tensile strength and canbe manufactured at a much lower cost than a tape composed of ribbons offabric. here cost isrnot the controlling factor, silk or otherfabricribbons' may be used. Accordingly, the invention broadlyconsidered relates to folded sheet material and the following claim isto be construed in this-lightexcept Where paper ribbons are expresslydefined.

hat I claim is:

A rope markerconsisti-ng of a "fiat paper tape comprising a singleribbon of paper,

said ribbon being Wound in overlapped spiral convolutions and saidoverlapped convolutions permanently pressed into a substantially fiattape.
